Have someone also problems with BFD in combination with OSPF on version 6?
When I enable this combination , the OSPF starts breaking every cca 10 minutes.
In version 5.20 I never had problems

Same here with 6.1
Before upgrade, everything was fine with BFD.
All BFD neighbors stop responding after some period of time (minutes). It happens when BFD is enabled on the remote side, not if only enabled in local. Remote nodes are mixed versions: 5.21, 6.0, 6.1 with no significant differences.
Log shows:
discarding BFD packet: neighbor not found

Hello, now in 6.24 is this BFD problem problematic for anyone ?
at the moment iam busy experimenting with it in combination with OSPF in Lab, but cant get it stable ?
BFD doesnt see neighbours randomly.

Strangely we are using BFD+OSPF on RouterOS 6.5 and 6.19 with no issues.

I've ran into this on various hardware. Usually a reboot of the router solves the problem. If I have one peer having problems I reboot the peer, if it's all peers I reboot the core and problem goes away.
I've seen this on:
CCR-1036
RB100AHx2
RB750UP
RB2011
But strangely I don't recall it happening on our CCR1009's
All routers are running a 6.2X version.

Generally I don't have any issues with BFD either. At least not the ones mentioned on this thread.
But occasionally if one peer goes down, BFD may drop all the other peers as well without any reason (no packet loss or anything on other peers).
Thankfully this occurs rarely, but it does occur (and I have seen this behavior on multiple installations) and it kind of defeats the purpose of a quick failover in routing when problems occur
